is forced to pass through the packages alternately in opposite directions.

An important object of the invention is the provision of a novel and convenient structure for the dyeing kier whereby a more uniform distribution of the incoming dye is effected.

A further object is the provision in a construction of this character of means whereby a sample may be readily withdrawn from the kier to determine the progress of the dyeing operation.

A still further object of the invention is the production of a kier of this character which may be readily manufactured and which is convenient in operation.

A further object of the invention is the production of a novel by-tank construction for use in such dyeing apparatus wherein means are provided to insure proper mixture of the dyestuifs withtheir liquid carriage immediately upon introduction of such dyestuffs to the system.

A further object of the invention is the production of an arrangement such that an entirely closed circulation cycle maybe established, thus enabling the apparatus to be conveniently and efliciently employed with vat and indanthrene colors without danger of oxidation of the. dyes during the dyeing process.

These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration I have shown a preferred embodiment of my invention and wherein;

Fig. 1 is a plan view of dyeing apparatus con structed in accordance with my invention;

Fig. 2 is a side elevation thereof; I I Fig. 3 is an enlarged vertical sectional view through the kier;

Fig. 4 is a similar sectional view through the by-tank;

Fig. 5 is a plan view of a slightly modified kier construction;

Fig. 6 is a horizontal sectional view therethrough;

Fig. '7 is a vertical sectional view therethrough; and

Fig. 8 is a vertical sectional view through the inner'wall element.

Referring now more particularly to the drawings, the numeral 10 generally designates the dyeing kier; 11, a by-tank associated therewith; 12, a pump for circulating dyestuffs in the kier and by-tank; and 13, a four-way valve for controlling the discharge of the pump so that this discharge may be directed to the kier at either of two inlets, while the other of the inlets is comiected to the by-tank; The kier comprises a side wall 14 including spaced inner and outer wall sections defining a chamber 15 therebetween, a bottom 16, and a cover 17. The chamber 15 is sealed at its upper and lower ends and the outer wall section of the side wall 14 has two vertically spaced inlets 18 for connection withone port of. valve- 13. The inner wall section is perforated with, a great number of perforations .19 which are preferably substantially uniform in their distribution. The bottom wall 16 is provided with an axial port 20, the inner end of which is formed as a downwardly tapering seat 21 for co-action with the tapering outlet fitting 22 formed on the lower ends of yarn carriers 23. Each yarn carrier 23 is in the'form of "a hollow drum having projecting flanges 24 at its upper and lower ends. Extending outwardly from the drum and communicating with the interior of the drum are the usual hollow spindles 25 for the reception of yarn packages 26. The upper flange of the yarn carrier has an aperture 27 and immediatelybelow this aperture the drum has an angle fitting 28 one end of which communicates with the interior of the drum and the other end of which mounts a vertically directed spindle 29 which projects through the opening 27 and is, accordingly, accessible above the upper flange. The cover 17 is provided with clamping hold-down means-30 of any usual or preferred construction for forcing the yarn carrier 23 into position in the tapering opening 21 and to hold the yarn carrier in vertical position. This cover, which may be provided with any of the usual means for insuring its proper sealing engagement with the side walls, as suggested at.31, hasformed therein an opening 32 vertically overlying the spintile 29, which opening is defined by a cylindrical wall mounting a swinging U-clamp 33 having a pressure screw 34 projecting therethrough for engagement with a closure cap 35 for the opening. Quite obviously, by releasing screw 34 and opening'cap 35 a yarn package 26 disposed on the spindle 29 may be removed for inspection.

In Figs. 5 to '8 inclusive I have illustrated a slightly modified construction particularly adapted for use in dyeing apparatus for dyeing yarn in smaller lots than the apparatus illustrated in Figs. 1 to 4. In this construction the kier 10 a, instead of having its outer wall formed as a single double-walled casting, is made in two separable sections, the one constituting the inner wall 14-a being perforated with the perforations 19. The upper ends of these sections have co-acting flanges F through which the sections are bolted together; the lower ends of the sections are secured to the bottom plate l6-aby bolts and studs as indicated. Such an arrangement facilitates both construction and cleaning of the kier.

The by-tank comprises a receptacle 36 having circulation openings 3'7 and 38 in itsside and bottom walls. The opening 37 communicates with one port of valve 13 through aconduit 39 while the port 38 communicates with the intake of the pump through a conduit 40. The discharge of the pump is connected to a further port of valve 13 through a conduit 41. As hereinbefore set forth, a third port of valve 18 is connected to the space through a branch constuffs introduced to the by-tank will be given an initial mixing in this inlet chamber, a furthermixing when passing through the perforated partition 44, and a very considerable agitation and, finally, complete mixing during their passage through a centrifugal pump through which they must pass in order to reach the kier. By manipulation of the four-way valve 13, the centrifugal pump may be caused to discharge either to the interior of the yarn carrier or to the chamber 15. Liquids delivered to the pump 12 are introduced into the kier in substantially uniform quantities throughout the extent of the walls of the kier so that the dyeing of the packages will be substantially uniform. When the fluid is delivered to the interior of the carrier it must, of course, pass through. the packages in order to reach the openings 19 and chamber 15 for return to the by -tank and pump.

As the construction illustrated is capable of a certain range of change and modification without in any manner departing from the spirit of the invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1'. In dyeing apparatus and in combination, a

' kier comprising a side wall including continuous spaced inner and outer walls defining an annular chamber therebetween, a vertical package carrier within thekier and comprising a hollow drum having perforated tubes projecting from the side wall thereof for the reception of yarn packages, the inner wall of said kier being perforated with perforationsdistributed substantially uniformly throughout such wall, means for introducing dyestuff to the kier through said chamber or through said package carrier, the tubes of said package carrier including avertically directed tube disposed-at the upper end of the package carrier, a closure for the kier having an opening aligned with said tube to permit removal of a yarn package from said tube with out opening of the kier closure, and asealable cover for said opening.

2. In dyeing apparatus, a kier comprising a side wall including continuous spaced inner and outer walls defining an uninterrupted annular chamber therebetween, means for introducing dyestuff uniformly to said chamber, the inner wall of the chamber being perforated with perforations distributed substantially uniformly throughout such wall, said inner and outer walls comprising separate units secured together at their upper ends, a bottom wall for the kier to which .the lower ends of the inner and outer walls are secured, said bottom wall having a port therein, a closed drum remov'ably positionable within the inner wall of the kier and'having an opening in its bottom wall defined by an element having sealing connection with the opening wall of the kier, and means to support yarn packages from the wall of the drum and in communication with the interior thereof.
